Document Summary

How much error is in the estimate. Bell shaped curve, normal curve: random samples selected then statistic is calculated, sample statistics provided by these samples will be distributed around population parameter. Central value of normal distribution is parameter (average: distribution is spread around that central value, distribution of sample averages. How close samples are clustered around the real value. Distance between actual value and the parameter. On average, how far is sample from population: measured in units. Difference between mean in sample and mean in population. Average distance between standard line and value. Measure how tightly grouped points are or how spread out they are: the more they are spread out, then standard error is larger, how big of an error. P is how much of the population - 35%= 0. 35. N is number of cases in each sample = 100 people in a sample eg q = 1-p.
